Missy recently has started having problems when going on walks she is pulling really badly and every little noise her ears prick up and she starts looking all over the place and won't listen to me. It's especially bad when walking by the two houses which have outside dogs. She knows that the dogs are there and will run up to her. Missy's misbehavior on walks just started when we ran into my neighbor who was walking his husky without a leash, (I know some people don't see a problem with walking a dog off leash cause their dogs behave but I don't trust Missy around other dogs so it frustrates me when dogs aren't leashed) so Koda, the husky comes toward us she didn't try to greet Missy but her being near Missy was enough for Missy to start pulling toward us. the next to days Koda came running up to me from her yard once again Missy was pulling really badly. Since this happened Missy has been horrible on walks. What can I do to get her to start behaving on walks again?
